There are some hurdles that are needed to overcome though, the first of which is actually creating the perfect environment for the plasma to exist within.

Not only does it need to be a perfect vacuum but it has to be in perfect stasis so it doesn’t react with any other elements within the reactor. As you can see from this video below even the tiniest impurity can cause little ‘specks’ to appear throughout the plasma.

Fusion reactors differ from the conventional nuclear reactors we see today by fusing two atoms together, rather than splitting them.

The only truly functional fusion reactors we know of are stars, however as humans get closer and closer to perfecting the technique this could all be about to change.
